Host
Add the following lines to /etc/rc.conf:
nfs_server_enable="YES"
mountd_enable="YES"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
rpcbind_enable="YES"
Set the sharenfs property to the dataset you want to share. Replace the IP
and pool/dataset with your desired values. ZFS properties are documented in
zfsprops(8):
# zfs set sharenfs='ro=192.168.1.0/24,-alldirs' pool/dataset
Start the NFS server:
# service nfsd start
# service mountd reload
Guest
Acquire the host’s IP address using ifconfig(8) on it first. We’ll assume it’s 192.168.1.5.
Mount the filesystem. /foo corresponds to the actual mount point of the
dataset in the host:
# mkdir -p /mnt/foo
# mount -t nfs 192.168.1.5:/foo /mnt/foo
If and when done, unmount it:
# umount /mnt/foo
In case you want the filesystem to be mounted on boot, add the following line
to /etc/fstab:
192.168.1.5:/foo /mnt/foo nfs ro 0 0
